When Hydrogen Is Passed Over Hot Tubgsten Oxide (WO3) WO3 + 3H2 ----------------> 3H2O + W
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
When hydrogen gas is passed over heated copper II oxide in a combustion tube, the copper II oxide will be reduced, resulting in the formation of copper metal and water. The color change from black (copper II oxide) to brown (copper metal) can be observed in the tube, along with the release of steam.
When ammonia is passed over hot cupric oxide, it reacts to form nitrogen gas and water. The reaction can be represented by the equation: 2NH3 + 3CuO → 3Cu + N2 + 3H2O. This reaction is an example of a redox reaction, where both reduction and oxidation occur.
When sulfur dioxide gas is passed over solid calcium oxide, a chemical reaction occurs to produce solid calcium sulfite. The reaction can be represented by the equation: SO2(g) + CaO(s) -> CaSO3(s). This reaction is used in industries to remove sulfur dioxide from gas emissions.

Assuming it's copper(II) oxide, the equation for that reaction is: CuO + H2 --> H2O + Cu. Reactants: copper oxide and hydrogen gas. Products: Water and copper. Elements present: hydrogen, copper. Compounds present: copper oxide, water. Metals: copper. Non-metals: hydrogen.
When hydrogen reacts with copper oxide, it reduces the copper oxide to form copper metal and water. This is a redox reaction where hydrogen acts as a reducing agent and copper oxide is oxidized. The balanced chemical equation for this reaction is: 2H2 + CuO -> Cu + H2O.
the copper oxide will turn red
When steam is passed over hot iron, the reaction produces iron oxide and hydrogen gas. The amount of hydrogen gas produced depends on the reaction conditions such as temperature, pressure, and quantity of iron. From the balanced chemical equation, for every mole of iron that reacts, one mole of hydrogen gas is produced.
When air is passed over heated copper powder, the copper undergoes oxidation, forming copper oxide. Copper oxide is black in color, which is why the heated copper powder appears black when air is passed over it.
Hydrogen gas is produced.
